The Public Utilities Commission of Sri Lanka decides that no revision of electricity tariffs is required for the last quarter of 2026

The Commission observed that the cost of supplying electricity increased by 2.88 per cent in the last quarter of 2026, as per the cost data submitted by the NSO. The updated cost data was also submitted by the NSO on 9^th November 2026. Taking into account the latest data and the views and Comments presented during the public consultation, the Commission has decided that no revision of electricity tariffs is required for the final quarter and that the tariff system in place in the third quarter will remain in effect during this quarter as well.

In accordance with Section 29 of the Sri Lanka Electricity Act No. 36 of 2024, the NSO is tasked with submitting estimated cost data for future electricity supply to the Public Utilities Commission of Sri Lanka (PUCSL) for review.

The NSO was required to submit the data for the final quarter of 2026 by August 17, 2026; however, the submission was made on October 6, 2026. The cost data indicated a potential 2.88% increase in electricity tariffs. Nevertheless, taking into account the proposals presented during the public consultation process, the PUCSL decided not to implement any revision to electricity tariffs for the final quarter of 2026.
